Radio

A headware radio can transmit or receive on any frequency, though it can only hold Rating x 2 programmed frequencies in its memory at any one time. The signal quality is rarely as good as a telephone, but the ability to switch bands makes the system more popular with the military or any user expecting active jamming. When transmitting, the user must speak, though he may do so in tones inaudible to those nearby. For the cost- or health-conscious, receiver-only models are available.
